To prevent oxidation

J. C. Tarafdar

@ Dadfar, may be the nitrogen-containing ester is substantially free of tritratable acidity.

Jesper Brask

Or to prevent hydrolysis of the activated acid? So oxygen is not the problem, but moisture in the air.

S M. Mahdi Dadfar

@ Paul Thanks for your reply. Yes, you're right maybe we will have oxidation in the presence of oxygen

Jesper Brask maybe, but anyway thanks for your reply

J. C. Tarafdar I think so . Thanks
